But the build still breaks, this time with another error - (so I don't look that much stupid any more..! :) CC kernel/extable.o CC kernel/params.o CC kernel/posix-timers.o CC kernel/kthread.o CC kernel/wait.o CC kernel/kfifo.o CC kernel/sys_ni.o CC kernel/posix-cpu-timers.o CC kernel/rt.o CC kernel/latency.o kernel/latency.c:854: error: `NR_syscalls' undeclared here (not in a function) x86_64 doesn't seem to be defining NR_syscalls anywhere.. Shouldn't it be part of unistd.h as other arches do? .config after make oldconfig is attached.. Parag
